. appuamiiaieaneember19,1913. 'serialnoeoaeee T0 @ZZ whom 'it may concern Be it known that l., llniniriirli.' Meer, a citizen of the VUnited States, residing at Ar in the county of Douglas and State of lil rois, have inverted certain new and useful .improvementsin Hitchine; levices for Tractioningines, of which the following is a specieation.y

This invention relates to traction engines, and it has particular reference to an im proved hitch for' coupling a traction engine to a vehicle or .implement such as a threshingr nrchine. corn Sheller or the like which is los drawn thereby.

A special object of the invention ist@ pro- Vide a bitching device of-simple and iin- -proved'construction which may he shifted transversely with respect to the tractor, thus enabling the vehicle or implement that is to be moved lto be placed some distance .either to the right or to the left of the een` tral medial line ofthe tractor and thus enabling .such vehicle or implement to' drawn closer up to the side of abuilding than would otherwise be feasible.

fi further object of vtheinvention is to simplify ant'jirn'prove the construction and operation of the hitch. particularly vith a view of producine` a hitch casingwhicli will t durable., as well as capable .of any strain to which it islliabl'e to and other ends in yview which pear as the nature of the in- Vei'ition r- .better understood. the same con-` in the improved construction and novel construction and combination of parts which hereinafter fully .desc ibed and para.' pointed out in the claims.

in. the accompanying drawings'has been illustrated a simple and preferred forni of the invention7 it being. however, understood that no limitation is necessarily made to the precise structural details thereinl exhibited, buty that changes, alterations and modificawill ferar 'tions-within the scope of the claims may be resorted to when desired.

Corresponding parts in the several figures are denoted by like characters of reference.

The franie of the tractor includes, the sills which are extended rearwardly to forni arms or brackets 16 for the purpose of n supporting the bitching device. i lThe housing for casingr lof the bitching deviceis formed principally of three angle bars or Lshaped bars of steel or other material.

*TWO of these bars 17 #and 18l are supported on the brackets 16'in somewhat spaced relation, the opstanding anges of said. angle bars constituting, respectively, a portion of the rear wall and the. front wall of the casing or housing. The third angle -bar 19 is supported in an inverted posi-tion directly ahove the angle bar 17 by means of obliquely disposed arfnis or brackets 20, the -lower ends of which 'are riveted or. otherwise secured` on the sills 15, while the horizontallange of the angle bar 19 is riveted .or otherwise secured on saidbrackets,l the vertical flange 'of sai l angle bar constituting a portion of the rear wall of the housino.- |The housing. it will be seen, is thus Vformed lof three angle bars arranged at three corners of a rectangle. the fourth corner/ being .occupied by the obliquely disposed brace 20.

Fitted in the housing is a blocker slide.

having three rectangular corners 'fitted in the angles ofthe bars 17, 18 and 19. said slide having alsoan obliouely disposed side E22 to avoid interfering with the brace members Q0, The end walls of theslide 21 are formed with arcuate recesses 23and it has a transverse threaded bore extending between said recesses. l Secured upon and .firmly connected with'the slide 2l is av yoke Q5 which Vextends rearwardly; through the. space Q6 between the vertical flanges of the bars 17 and 19. said yoke having a swelled portion 26 which is apertured for the passage of a hitchinar bolt 27 having 'an eye'QS at theV rear end thereof. Said bolt is also provided'with a nut 29 .between which and the yoke Q5 is positioned a coiled Spring 30 which surrounds the shank of the bolt.

The housing at the ends .thereof is. sur! rounded by hoops or bands 3 1. one at each end serving' to reinforceV the construction by preventing the angle bars 17. 18 and 19 from lio spreading apart at the ends. Mounted in' a box or bearing member consisting of loiver and upper parts 32,' 33 having interengaging dowels and sockets 34, 35 in.I the ,meeting` faces thereof and retained in position within the housing by fastening means. such as set screws' 36, for the reception of the points of whichthe box members may be provided with recesses, as 'indicated at 37.' By this construction, the parts of the device may be very readily assembled or taken apart when requiredfor any purpose. The boxings afford bearings for the ends of the shaft 38 .Which is externally threaded for engagement `with the threaded bore 2e of the slide 21, which latter by rotation of the shaft may be movedtransversely toward either end o'f the housing. V i

The shaft 38 is extended at vone end through its bearing, and it carries ,a bevel pinion 39 meshing with a beveli pinion'lO on a ,shaft 41, 'said shaft having at one end' a crank 42 -Wh'ereby it maybe conveniently vrotated for the purpose of rotating the screw whereby the rslidel 21 is moved in either direction.

IThe tractor has been shown as equipped,

withl a shaft .43 which constitutes a steering shaft and .which is equipped With the customary hand wheel or crank 44. rll`he steering'device is conventional and'is no vpart of the present invention.

(From the foregoing description taken in connection with 4the drawings'hereto annexed. the operation and advantages of this invention will be readily understood.

The invention isl simple in construction yand is capable ofybeing readily applied to almost any tractor of ordinary constructionlit beingl understood that-'While the bitching device ,has been shownv as being mounted onA the rearwardly extended ends ofthe sills ofthe frame of the machine, and

45 While this construction is preferable, any

tractor frame may be equipped .with brackets or 'supports Whereon the bitching device may'bemounted. the invention residing essentially in the improved construction of the housing and the assemblage of the parts. llt is also desired to point out the special constructionof the slide 2l herein shown as peculiarly` advantageous; said slide should be of liberal length iu order that the strain may be distributed upon the which it is provided.

t vehicle'o-r implementfudrawnby thetractor the housing ad'iacent to each end thereof is' l -Which the parts of the vdevice mayA be .disassembled for repairs or other purposes by simply loosening the set screws' 36 suliciently to enable the bands 31 and the box members 32,

33 to be. detached, is this' that the space'between the angle bars-17, 1.8 presents a slot or opening that Will prevent the accumulation v of dirt Within the housing. thereby obstructing the operation of the slide 21, as would be the case if thel housing were constructed withl a solidbottom.

The general. construction "is simple and. thoroughly efficient for the. purposes for `Having thus described the invention, lWhatl bar supported above the rearward angle bar,
